No _automatic_ migration? colinux+oM 2.4.26-1

Hi, 

I'm a newbie of oM cluster. I set up a cluster on 7 computers using
            winxp+colinux0.6.1+oM2.4.26.1+NFS+/dev/net/tun virtual net.
The nodes are connected with a virtual network 10.55.44.xx (since I have 
to use
the ics/nat function of xp). There is no regular linux box in the cluster.

Now there are only two problems left. One problem is the floating point 
error of the
'gettimeofday' system call. The other problem is that there is no 
automatic migration
of processes.

If I use 'mosrun -2 ./a.out', the process can migrate correctly. But 
there is no automatic migration,
no matter how high the load is. I recompiled the om tools but the 
problem is still there. What could
be the problem potentially? Could you give me a hint?

Thanks a lot
